The United States high school admission process typically requires students to meet certain academic criteria, primarily through their high school GPA and standardized test scores such as the SAT or ACT. The average high school GPA required for admission to a four-year college or university is around 3.0 to 3.5, with many competitive institutions expecting a GPA of 3.5 or higher. Standardized test scores also play a significant role, with the average SAT score being around 1080 and the average ACT score around 22. These requirements are based on data from the National Center for Education Statistics (NCES) and the College Board, which provide insights into the average academic performance of high school graduates and their admission outcomes. The emphasis on GPA and standardized test scores reflects the institutions' desire to admit students who have demonstrated a strong academic foundation and the potential to succeed in a college environment.
